JAMES BOLTON, OF RICHMOND, VIRGINIA.

HOT-AIR FURNACE.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, JAMES BOLTON, doctor of medicine, of the city of Richmond, in the county of Henrico and State of Virginia, have invented a new and Improved Mode of Constructing WVarm-Air Chambers; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in dividing an air chamber (surrounding a stove, furnace, pipe or other contrivance for heating air) by partitions into separate compartments, each of which is to be connected with one or more separate warm air fines, so that each flueor set of fines may be supplied with warm air from that compartment exclusively with which the flue or set of fines may be connected.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my warm air chamber according to the plan described in my specification of an improvement in warm air chambers for which Letters Patent of the United States were issued to my assignee, Charles D. Yale, dated the twenty-sixth day of April, one thousand eight hundred and fifty three, because I consider this the best form of air chamber and almost the only form adapted to the improvement herein described; but in order to obviate the inconvenience usually arising from some of the apartments which are designed to be warmed receiving less than their due proportion of warm air (which is well known to be a usual occurrence owing tosome apartments being more favorably situated in regard to elevation and proximity to the air chamber and consequently drawing off more than their due supply of warm air, an inconvenience which is especially liable to occur when there is a moderate fire in the furnace and consequently a moderate supply of warm air by the chamber) I attach one or 10,333, dated December 20, 1853.

more sheets of iron to the wall or inclosure of the air chamber by their outer edges, placed in a vertical direction, their faces being placed in radii passing from the vertical axis of the furnace, and I attach their inner edges closely to the opposite external surface of the furnace. I thus place vertical airtight partitions-in my air chamber, as shown at letters A A A A. These partitions I fasten accurately together in the center of the chamber where the furnace or pipe is wanting. The upper and lower edges of these partitions I attach to the upper and tinuous conduit to the apartment for which it is designed. At the upper part of each of these partitions I place a valve B, for the purpose of throwing the air of two or more compartments into one, if it shouldbe desired. I enter the upper part of each of these compartments by one or more warm air flues, which are supplied with Warm air by the compartment to whichthey are attached. When the warm air rises in the compartments as, described it cannot pass from one to another unless the valve between them be opened; nor can it pass from a single compartment to any other flues than those with which it is connected.

What I claim as my invention and desire to secure by Letters Patent is v The division into compartments of the air chamber surrounding a stove, furnace, pipe be drawn off by fiues from each compart- .9 1,

ment without interfering with the supply of warm air from the other compartments.
